Increasingly tough legislation is driving the demand for improved energy efficiency in the home, with the UK Government committed to reducing CO2 emissions by 80% from 1990 levels, by 2050*2. This means a reduction of at least 34% in greenhouse gas emissions by 2020. It’s clear that to achieve these ambitious goals, our approach to energy use and the way we heat our homes has to change. Pivotal to this change is improved energy efficiency and a greater use of renewable energy. Air source heat pumps use free renewable energy from the outside air and upgrade it for use in the home. Why Ecodan air source heat pumps are an ideal alternative to traditional heating Recognised as a renewable technology by both UK and EU Governments, heat pumps provide an effective, energy efficient alternative to traditional heating systems. Ecodan uses advanced technology to heat homes and hot water using energy absorbed from the outdoor air. As perhaps the single most important renewable solution, heat pumps are an established, proven technology, supported by Government incentives, economically viable and flexible in their application for domestic heating. Significantly, the Committee on Climate Change recognise that heat pumps could meet up to 75% of the total residential heat demand in the UK*1. Over the last decade continual developments and major advances such as the introduction of variable capacity control have helped to position Ecodan air source heat pumps as the market leader. Mitsubishi Electric has now introduced self-learning controls to ease use along with a quality-assured, British-built cylinder which can reduce installation time and costs. *1 The Renewable Energy Review, May 2011, DECC / Committee on Climate Change *2 Pathways 2050 Page 5

By using an Ecodan to provide space heating and hot water, it is possible to reduce a home’s CO2 emissions and running costs. Ecodan uses inverter-driven heat pump technology to harvest and upgrade free, renewable energy from the outdoor air to deliver heating and hot water, even in temperatures as low as -20°C. For every 1kW of input electrical energy, Ecodan harvests and upgrades renewable heat from the outdoor air to provide the home with an average of at least 3kW of heat output.*3 Outstanding benefits: Achieves level 4 of the Code for Sustainable Homes with no additional measures and can be even higher when used in conjunction with other improvements Improves energy use leading to lower running costs and CO2 emissions Qualifies for the current Renewable Heating Premium Payments (RHPP) and upcoming renewable heating incentives planned by the Government 5% VAT rating on capital and install costs Self-contained outdoor unit only requiring water and electric connections No gas supply, flues or ventilation required, therefore poses no carbon monoxide risk Low noise levels - Ecodan has achieved the Noise Abatement Society’s Quiet Mark MCS approved *3 The overall system efficiency and energy savings will depend on the comparison with your current heating system, satisfactory system design and installation, and operational settings i.e. how you use the heating system.

As a nation we are now creating new and existing low carbon houses, yet around 75% of existing homes will still be in use in 2050, so to a large extent our future housing stock is already built. If we can find ways of easily improving homes the efficiency of existing buildings we can make a dramatic difference to both CO2 emissions and energy use. Ecodan provides a proven, efficient way of heating homes. It can achieve level 4 of the Code for Sustainable Homes, and even higher when used in conjunction with other improvements such as Photovoltaics. Air source heat pumps are now covered by Permitted Development legislation because they can improve the efficiency of existing buildings although noise levels must be taken into account. Ecodan is recognised by the Noise Abatement Society and has received its prestigious Quiet Mark accreditation. Before considering any heat pump, Mitsubishi Electric strongly recommends that basic thermal improvements are undertaken in these properties to provide the highest levels of thermal efficiency. These can include cavity wall insulation, loft insulation and double glazing. In recognition of Ecodan’s status as a low carbon technology, the cost of VAT is reduced to 5% as opposed to the standard Ecodan 8.5kW air source heat pump rate of VAT applicable on all traditional heating systems. *4 BRE Digest of UK Energy Statistics Page 7

DOM HEAT BRO TO PRINT_spreads 29/05/2012 11:27 Page 15 How Ecodan Heat pumps take electrical energy and low grade heat energy from the outdoor air to heat refrigerant air source heat which in turn heats water for domestic use and space heating. The efficiency of a heat pump is known as the Coefficient of Performance or CoP. This is pumps work a ratio of the heat delivered to power consumed. The operation of a heat pump is similar to a refrigerator - but in reverse. This process is known as the vapour compression cycle and the following is a more detailed explanation. *8 At the beginning of the first phase the refrigerant is a cold low pressure liquid. 1. The refrigerant passes into the evaporator and heat energy from the outside air passes over the evaporator causing the refrigerant to increase in temperature and change to a hot gas. 2. This hot gas then enters the compressor where its temperature increases further as a result of the compression process. 3. The hot refrigerant gas is then condensed as it passes across one side of a plate heat exchanger. The heat is transferred to the cooler side (water side) of the heat exchanger, and this is transferred via the primary water circuit to heat up the water tank inside the property. As the temperature of the refrigerant decreases the state changes from a gas back to a cool liquid. 4. Despite dropping in temperature, the cool liquid still has a high pressure and to reduce this pressure the liquid refrigerant passes through an expansion valve. This causes the pressure to drop and the temperature lowers, returning the refrigerant to its initial state of cool low pressure liquid. This process is repeated. It is only the refrigerant that passes through this cycle; the water is heated as it travels through the plate heat exchanger. The heat energy from the refrigerant passes through the plate heat exchanger to the cooler water which increases in temperature. This heated water enters the home heating circuit and can also be used to provide domestic hot water via a hot water cylinder. Page 14

Recognised by the Noise Abatement Society as quiet to run (45dBA)*9, Ecodan is quick to install, rivals traditional gas or oil heating systems in its ease of use and easily meets renewable energy targets. Ecodan achieves high levels of efficiency because the system allows the lowest flow temperature to be targeted whilst still maintaining the desired room temperature. It does this by using room temperature as well as outdoor temperature, making the system respond both faster and more accurately, creating a more stable and comfortable home while maintaining system efficiency. *8 As independently tested by BSRIA based upon BSEN14511 Part 3 standard rating conditions. Due to the method of operation, the performance of heat pumps will vary based upon the temperature of the heat source and the requirements of the heat delivered. The BSEN14511 testing relates to the heat pump performance only and not the entire heating system. *9 5kW unit measured at 1 metre Page 15

The properties included a newly built 3-bed terraced house, a 1950’s 4-bed semi, a large 5-bed detached home, built in 1999, and the BRE Visitor’s Centre in Watford. During the trial period, temperatures dropped as low as -10ºC, but Ecodan still delivered the performance necessary, proving that they will cope throughout the year in a variety of different properties and heating configurations. The Ecodan units in the properties delivered COPs*10 ranging from 3.0 to 3.33, despite the low temperatures. A level of 3.33 shows that 2.33kW of renewable energy is being harvested from the surrounding air for every 1kW of electricity used. The live trials showed that Ecodan air source heat pumps really are ready to become the most viable, mass-market alternative to gas and oil-fired heating. *10 Coefficient of Performance (COP) is a measure of the useful energy a system can deliver compared to the energy it consumes.

They can drill down further and see how the unit is performing at any time of the day, week, month or year, and see the running costs, CO2 emissions and energy consumed, when compared to gas, oil and direct electric systems. The properties use a mixture of the three Ecodan models (5kW, 8.5kW and 14kW) working with both radiators and under-floor heating to demonstrate how the systems can work best. Anyone can quickly see the annual performance of each property.

As an and larger radiators environmentally aware family who recycle wherever possible and insulate their home to preserve energy, they were keen Installation took 2 days to find a heating system that was more efficient with less impact on the environment. Unable to use gas, they considered ‘greener’ alternatives to oil, such as wood, solar thermal and biomass, but all of these seemed to prove either insufficient for their needs or too involved to install, run and maintain. Replacing their old oil-fired heating system, which had become increasingly inefficient over the 15 years they’d had it, they found Ecodan to be much more efficient and effective to run. Being able to get rid of all the old water tanks and pipes in the loft freed up a lot of space and having installed larger, more efficient radiators throughout, their home is now warm enough without the need to boost the heating with log fires, as they previously would have done. Unlike other residents in the village, the Fox family no longer have to rely on increasingly expensive oil to heat their home and by converting to Ecodan, from their initial heating bill, they estimate an annual saving of £500. In addition, with Ecodan they enjoy a more even temperature throughout the house. The new system also provides them with copious amounts of hot water - more than enough for even their two teenagers who live in the shower!

A powerful, renewable energy solution was required. With inconsistent levels of comfort coupled with escalating gas bills, this home stood to benefit substantially from a more efficient means of heating. Unlike the ageing gas system that was previously installed, Ecodan uses the latest technology to harvest renewable energy from the outside air to provide central heating and hot water. Easy to install, the advanced efficiency of Ecodan, is perfect for this 1950’s home. Using Ecodan to replace the inefficient gas boiler and installing larger radiators to work with the lower flow temperatures, means this home enjoys constant comfort levels for a fraction of the cost of the old gas boiler. Able to supply all the heating and hot water this property needs, Ecodan is the ideal, low carbon replacement these homeowners needed.
